Specification of Letters Patent.

Patented Nov. 8, 1910.

Application filed March 15, 1910. Serial No. 549,476.

To all whom it may concern:

Be it known that I, CHARLES M. HICKEY, a citizen of the United States,residing at Stockton, in the county of San 'Joaquin, State ofCalifornia, have invented certain new and useful Improvements inDredger- Buckets; and I do declare the following to be a full, clear,and exact description of the same, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the characters of referencemarked thereon, which form a part of this application.

The invention relates to dredging and excavating paraphernalia andparticularly to the digging and dredging bucket thereof, the object ofthe invention being to produce a combination clam shell and orange peeldredger bucket whereby when soft easy digging is encountered, then theclam shell feature may be used, and when the surface being dug is hardand not easy to excavate, then the pointed structure of the orange peelfeature of the bucket may be used.

A further object of the invention is to roduce a strong durable bucketand one which will be simple and inexpensive and yet exceedinglyeffective for the purposes for which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views.

Figure 1 is a side elevation of the complete bucket. Fig. 2 is asectional view taken on a line w-w of Fig. 1. Fig. 3 is a fragopenposition of the bucket when used as a clam shell type of bucket. Fig. 4is a frag entary view of a bucket arm showing a bearing and bolt holetherein. Fig. 5 is a fragmentary view showing two bucket arms clampedtogether. Fig. 6 is a fragmentary view of folding bucket arms showing ahoisting means thereon. Fig. 7 is a fragmentary view of the lower end ofone half of my improved bucket. Fig. 8 is a perspective view of afilling bar. Fig. 9 is a sectional view of a bucket frame joint. Fig. 10is a sectional view taken substantially on a line y-y of Fig. 7.

Referring now more particularly to the characters of reference on thedrawings, I

first provide orange peel bucket spades 1 havmg suitable changeablepoints 2 and curvmg arms 3 and fender guards 4 from the arms 3 to theouter edges of said buckets 2 to dlscharge or shed trash or otherdeleterious material from the buckets. The arms 3 normally have bearingsat 5 in yokes 6 on a square frame composed of rigid side members 7having inwardly projecting arms 8 having embossed shoulders 9,connecting lmks 10 having normal bearings on said arms 8 at saidembossed portion 9 and when the bucket is being used as of the orangepeel type such links 10 are fixed rigidly by bolts as at 12 securingthem to the arms 8 and then the four points 5 are the pivotal points forthe four orange peel bucket sections 1, these points being diametricallyopposed as shown in Fig. 2, and one set of the curvlng and crossingoperating arms 3 proect first under the other set as shown in Fig. 1 andeach having suitable operating chains 13.

Now when it is desired to use the bucket as of the clam shell type thebolts 12 are removed from the links 10 and arms 8 and inserted throughthe yokes 6 and arms 3 as at 14: (see Figs. 1 and 3) which makes thearms 3 rigid with respect to the members 7 thus forming the two sets oftwo members 1 adjacent to said members 7 into a clam shaped buckethaving their opening pivotal points at 11. When this structure isemployed the two arms 3 adjacent to each member 7 are clamped togetheras at '15 to form said two arms together to act as one for each of theclam shell shaped buckets formed as aforesaid. Since the edges of thebucket sections 1 are sharp, when two of them are formed to a clam shellshape as described a V shaped groove 16 is formed between them and topreventanything lodging in said groove which might spring the buckets 1apart or otherwise injure them, I provide a filling bar 17 which fitsand fills said grooves 16 and may be secured to the buckets 1 by boltsthrough a flange 18 or other suitable means.

Each of the arms 3 has the usual dump chain 19. If desired, the arms 3may have yokes 20 secured to their outer ends and extending inwardly tothe chains 13 (see Fig. 6). This structure would be more advantageousthan having chains all the way, since the chains would rub and wear andnot be so conveniently operated as are the yokes.

21 are bumpers to prevent the arms 3 from striking the rectangular frameof the bucket if they move to a very low plane.

From the foregoing description it will be readily seen that I haveproduced such a dredger bucket as substantially fulfils the objects ofthe invention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention.

Having thus described my invention what I claim as new and useful anddesire to secure by Letters Patent is:

l. A dredger bucket comprising a frame having side members flexiblyjoined, means for holding said frame rigid, arms having bearings in saidframe, and bucket sections on said arms.

2. A dredger bucket comprising a' rectangular frame having opposite sidemembers flexibly joined, means for fixing said opposed side membersrigid with respect to one another, arms having flexible bearings in saidframe, means for fixing said arms rigid with respect to said frame, andbucket sections on said arms.

3. A dredger bucket comprising a rectangular frame comprising rigidopposite side members, inwardly projecting arms on said side members,links flexibly connectedwith said arms, means for fixing said linksrigid with respect to said arms, and a bucket means carried by saidframe.

In testimony whereof I aflix my signature in presence of two witnesses.
